Along with the Homebush railway station, the Dunc Grey Velodrome at Bass Hill represented a step forward in design and construction techniques due to the Sydney Olympics.

The curved roof of this premier cycling venue contains 12,000 l/m of C15024 and C25024 purlins curved through the x-x axis which required substantial research & development into tooling and rolling techniques.

Since the Olympics, Rollco continues to be the market leader in curved purlins for applications requiring C15024, C20024 and C25024.
